Taken from Oxfordshire, UK on the afternoon of 3rd April 2023. Because it was mid-afternoon when I started imaging, conditions were not great, but there was some nice activity visible on the Sun, and sunspot group AR13270 was looking lovely in H-alpha.

Taken with a Coronado PST and ASI120MC camera fitted with a 2x Barlow. A 1,000 frame video was taken using SharpCap, then the best 30% or 50% were stacked depending on the quality graph.

Processing workflow:

RGB alignment in Registax 6

Sharpening using Focus Magic

Remove all colour + processing in Lightroom

False colour added back in using Photoshop CS2

Forse fra le regioni più belle e suggestive del nostro satellite: gli Appennini.

La catena si divide in due tronconi, una più a nord e una più a sud. Nel loro insieme coprono una distanza di oltre 600km, molto simili quindi agli Appennini Terrestri, ma qui, al loro interno, troviamo vette con un'altezza di oltre 4000m.

Nella foto è inquadrata anche la zona del Polo Nord Lunare, dove il Mare Frigoris separa i crateri più settentrionali dalla zona di Plato, la Valle Alpina e i due Aristotele ed Eudoxus, in alto a destra. Poco sotto la Valle Alpina giace il cratere quasi del tutto sommerso "Cassini" che fa da guardiano a Aristillus, Autolycus e Archimede. In fondo alla agli Appennini, immerso nell'ombra, si trova il cratere Eratostene, del quale si vede soltanto la parte orientale del bordo. In basso a destra nella foto si trova il cratere Manilius.

Questa zona è ricca di altri dettagli interessanti, primo fra tutti la "Rima Hadely", nella parte Nord degli Appennini Centrali, sito di allunaggio dell'Apollo 15.

Di sicuro una zona che non ci si stanca mai di guardare!!

Nébuleuse du croissant - NGC6888

La nébuleuse du Croissant (NGC 6888) est une nébuleuse en émission située dans la constellation du Cygne, à environ 5 000 années-lumière

Elle est issue des rapides vents stellaires créés par l'étoile Wolf-Rayet WR 136 qui poussent la matière issue de vents plus lents éjectés par cette même étoile lorsqu'elle était plus jeune et plus petite (de type géante rouge) il y a 400 000 ans. Le front de choc engendre ce que l'on nomme une bulle de Wolf-Rayet.

Shot on 3/7/21 from Rain Drop Lane driveway on a cool evening, about 30F and calm winds. Sky was a Bortle 2, SQM 21.0 or slightly worse (due to neighbor lights). Subs 5 minutes, 85 minutes total exposure time, gain 120, cam temp -10C, ASI-294. Used Samyang 135 mm lens along with guiding by PhD and auto-dithering via SharpCap.

Visible in this image is a fairly beautiful Rosette nebula (looks better than subject in center), and also the tiny Hubble's Variable Nebula" (which looks like a comet). Cone itself did not reveal too much nebulosity. Also, feel that dithering was inadequate. Noise pattern is reminiscent of non-dithered work in the past. And the dithers were pretty small. Will need to adjust this in the future.

Note that IR cut filter was used, so stars were not bloated. Contrast this with other Cone image.

Used MultiscaleLinearTransform in PI for final smoothing (with k-sigma noise thresholding) to kind of smooth out some of the hash. Hope to re-shoot this image for more clarity and details. Also used PI's Starnet to help stretch the Ha.

M43, also known as De Mairan's Nebula, is a star-forming nebula with a prominent H II region 1600 ly away in the equatorial constellation of Orion. The De Mairan's Nebula is part of the Orion Nebula (M42), being separated from the main nebula by a dense lane of dust known as the northeast dark lane. It is part of the much larger Orion Molecular Cloud Complex.

from Wikipedia

NGC 7331, also known as Caldwell 30 (a.k.a. The Deer Lick Group), is an unbarred spiral galaxy about 40 million light-years (12 Mpc) away in the constellation Pegasus. It was discovered by William Herschel on 6 September 1784.

The galaxy appears similar in size and structure to the Milky Way, and is sometimes referred to as "the Milky Way's twin". However, discoveries in the 2000s regarding the structure of the Milky Way may call this similarity into doubt, particularly because the latter is now believed to be a barred spiral, compared to the unbarred status of NGC 7331.

In spiral galaxies the central bulge typically co-rotates with the disk but the bulge in the galaxy NGC 7331 is rotating in the opposite direction to the rest of the disk. In both visible light and infrared photos of the NGC 7331, the core of the galaxy appears to be slightly off-center, with one side of the disk appearing to extend further away from the core than the opposite side.

NGC 7331 is the brightest galaxy in the field of a visual grouping known as the NGC 7331 Group of galaxies. In fact, the other members of the group, NGC 7335, NGC 7336, NGC 7337 and NGC 7340, lie far in the background at distances of approximately 300–350 million light years.

All of the members of the NGC 7331 Group, along with NGC 7325, NGC 7326, NGC 7327, NGC 7333, NGC 7338, are listed together as Holm 795 in Erik Holmberg's A Study of Double and Multiple Galaxies Together with Inquiries into some General Metagalactic Problems, published in 1937.

Three supernovae have been observed in NGC 7331:

- SN 1959D (type II-L, mag. 13.4) was discovered by Milton Humason and H. S. Gates in a survey at Palomar Observatory on 28 June 1959.

- SN 2013bu (type II, mag. 16.6) was discovered by Kōichi Itagaki on 21 April 2013.

- SN 2014C was discovered by the Lick Observatory Supernova Search (LOSS) on 5 January 2014. The star underwent an unusual "metamorphosis" from a hydrogen-poor Type Ib to a hydrogen-rich Type IIn over the course of a year.

In addition to the confirmed supernovae, a 1903 photographic plate from Yerkes Observatory shows a magnitude 16.6 candidate transient that may have also been a supernova.

from Wikipedia

NGC 2775 , also known as Caldwell 48 , is a spiral galaxy in the constellation Cancer . It is 67 million light-years (20.5 megaparsecs ) away from the Milky Way . It was discovered by William Herschel in 1783. NGC 2775 belongs to the Antlia - Hydra Cluster of galaxies and is the most prominent member of the NGC 2775 Group , a small galaxy group in the Virgo Super-cluster , along with the Local Group . Other members of the NGC 2775 Group include NGC 2777 and UGC 4781 .

This object has a morphological classification of SA(r)ab, which indicates an unbarred spiral galaxy (SA) with a prominent ring structure (r) and flocculent , tightly wound spiral arms (ab). The galaxy is inclined by an angle of 44° to the line of sight from the Earth . The galactic nucleus is not active and the large nuclear bulge , which extends out to an angular radius of 0.4′ , is relatively gas free. An explanation for the latter could be a high supernova rate. Although star formation is taking place in the dusty outer ring, NGC 2775 does not display any current starburst activity , and the galactic nucleus is virtually free of any star formation whatsoever.

The galaxy's hydrogen tail feature indicates a past interaction with a faint companion. A satellite galaxy appears to have orbited NGC 2775 multiple times, losing mass as it does so and creating faint, shell-like structures. Nearby irregular galaxy NGC 2777 displays a tidal tail of hydrogen gas that points back to NGC 2775, suggesting the two may be linked.

One supernova has been observed in NGC 2775. SN 1993Z ( type Ia , mag. 13.9) was discovered by the Leuschner Observatory Supernova Search (LOSS) on 23 September 1993. By September 25, spectral analysis showed that it had peaked about four weeks earlier.

From Wikipedia:

Markarian 231 (UGC 8058) is a Type-1 Seyfert galaxy that was discovered in 1969 as part of a search of galaxies with strong ultraviolet radiation. It contains the nearest known quasar. Markarian 231 is located about 581 million light years away from Earth.

The Markarian 231 galaxy is now undergoing an energetic starburst. A nuclear ring of active star formation has been found in the center with a rate of formation greater than 100 solar masses per year. It is one of the most ultraluminous infrared galaxies with power derived from an accreting black hole in the center, and the closest known quasar.

A 2015 study suggested that the central black hole, estimated to be 150 million times the mass of our Sun, may have a black hole companion weighing in at 4 million solar masses, and that the duo completed an orbit around each other every 1.2 years.

However, that model was subsequently shown to be unfeasible.

Another study has found evidence for the presence of molecular oxygen (O2) by using submillimeter astronomy, the first time molecular oxygen had been detected outside of the Milky Way galaxy.

Bonjour à tous

je vous présente une petite image avec 3 galaxies principales et quelques petites en arrière plan

Messier 99 - Moulinet de l'amas de la vierge

M99 (ou NGC 4254) est une galaxie spirale située dans la constellation de la Chevelure de Bérénice

M99 fait partie de l'amas de la Vierge, et est classée de type Sc sur la séquence de Hubble. Phénomène peu courant, cette galaxie est « asymétrique », son noyau étant décalé par rapport au centre géométrique des bras spiraux

Elle est située à environ 60 millions d'années-lumière du système solaire, et s'en éloigne à la vitesse de 1 200 km/s

Nous apparaissant exactement par la tranche, la galaxie spirale NGC 4302 (en bas, sur la gauche) se trouve à environ 55 millions d'années-lumière dans la constellation de la Chevelure de Bérénice. Faisant partie du vaste amas de galaxies de la Vierge, son diamètre est d'environ 87 000 années-lumière, soit légèrement inférieur à celui de notre propre Voie lactée. NGC 4298, galaxie compagne de la précédente, est également une spirale chargée de poussières, mais orientée très différemment par rapport à notre point de vue

I had so many problems last night. Some serious guiding issues. Either the mount couldn't turn the gears properly or Sharpcaps Polar Alignment is giving me terrible results. Before the session yesterday I loosened the nut holding the RA bearings in place because RA felt a little sticky still, however I also discovered that my RA setting circle locking screw would cause RA to completely bind when it was even slightly tightened. I removed it but I should have re-tightened the main RA nut again as I think the setting circle problem was the actual cause.

Sharpcap said I had perfect polar alignment (0.04 arc/min) but my guiding was terrible and PHD2 Drift align said it was way out. This was 41-45s lights @ ISO 800 after I gave up on M33 due to guiding having issues. 30 bias, 73 dark, and 30 flats that didn't seem to do much.
